First of all, I would like to thank my advisor Prof. Dr. Thomas Rudolph. I enjoyed my time as his research assistant and I am very thankful that he enabled me to get such a deep and fascinating insight into the retailing industry. In the development of my dissertation, he gave me important advice and ensured that my ideas were convincing and relevant. I particularly enjoyed assisting him during various executive education seminars, where he showed me how relevant research results can be translated into impactful recommendations for practitioners. Also, during our numerous team events, his generosity was just remarkable. Furthermore, I would like to thank my co-advisor Prof. Dr. Günter Müller-Stewens for his help and suggestions in shaping my dissertation. I enjoyed our interesting discussions and he gave me valuable advice on how to build on the corporate diversification literature. In the starting phase of this dissertation, he also gave me important words of encouragement to investigate the topic of within-industry
